摘要：

Temperature and loading dependences on the rheological behavior and isobaric specific heat capacity of several suspensions of alumina nanoparticles in a binary mixture of [C(2)mim][CH3SO3] ionic liquid and water were experimentally determined to assess its potential condition of enhanced heat transfer fluids. Rheological tests show a clear Newtonian behavior for the base fluid and the NEILs with lower Al2O3 concentrations while higher amounts of alumina nanoparticles entail non-Newtonian fluids and increase in viscosity up to 78%. The heating-cooling viscosity tests reveal that no significant viscosity hysteresis occur and VFT equation adequately describe the temperature dependence. Isobaric specific heat capacities decrease (<10%) with nanoparticle mass fraction and increase (<10%) with temperature. The goodness of the Raud et al. correlation for predicting the isobaric specific heat capacity of nanoparticles enhanced fluids is discussed. (C) 2020 Elsevier B.V. All rights reserved.
